Try this
clf
f = figure();
ax = axes();
p = pie(ax, ones(1,5));
t = p(2:2:end);
p = p(1:2:end);
delete(t)
s = {'CC', 'ME', 'NU', 'BI', 'IA'};
for k=1:size(davar1, 1)
for i=1:numel(s)
switch davar1(k,:).([s{i} '_CHECK']) % I even tried insert (j) here and do it in the for loop but error says Index exceeds the number of array elements (2).
case 'New York'
p(i).FaceColor = 'g';
case 'California'
p(i).FaceColor = 'y';
case 'Illinois'
p(i).FaceColor = 'r';
case 'Texas '
p(i).FaceColor = 'k';
case 'Ohio'
p(i).FaceColor = 'b';
case 'North Carolina'
p(i).FaceColor = 'c';
case 'Tennessee'
p(i).FaceColor = 'w';
end
end
exportgraphics(ax, ['filename' num2str(k) '.png']);
end
